Question

I have an object called @events containing about 50 records being pulled from a find condition of my model.

I’m currently displaying the results of the @object in my view like this….

<% for event in @events %>
    <p><%= @event.name %></p>           
<% end %>

Instead of displaying the entire 50 I would like shrink the set to about 10 records so it displays better on the page.

I cannot use :limit in the find condition since the object is being composed from a variety of loops where after each iteration it adds a few specific records.

So the issue is I have this object @events with 50 records, how can I change the object after its been composed so only the first 10 records remain?

Answer 1

First of all, if you’d like to have pagination, I strongly suggest taking a look at will_paginate

Alternatively, you can do the following to read the first 10 records only.

<% @events.first(10).each do |event| %>
    <p><%= event.name %></p>           
<% end %>

Or the last 10 records

<% @events.last(10).each do |event| %>
    <p><%= event.name %></p>           
<% end %>

I didn’t test it but you get the point.
